1. The ITP winch is delivered to the ice by the helicopter, while the tripod is assembled over the location where the AOFB will be installed. (Rick Krishfield)

2. Mike Dempsey and Jeff Charters verify operation of all of the ice sensors on the IMBB immediately after deployment. (Rick Krishfield)

3. A Yale grip is applied to the wire suspending the ITP profiler by Jim Dunn (red coat) and Chris Newhall (on knees) with the assistance of Helicopter Pilot Chris Swannell (left), Seaman Dan MacLean (center), and Officer Cadet Julie Patrick (right). In the background, ice observers are examining ice cores, and others are working on assembling the wind generator for the AOFB. (Rick Krishfield)

4. An ice core is operated on by Heidi Isernhagen and Alice Orlich. (Sarah Zimmermann)

5. An electromagnetic sounder is used to detect the saltwater/ice interface beneath the floe for determining ice thickness along transects by Kaza Tateyama and Kohei Mizubata. (Sarah Zimmermann)

6. The black box which contained the AOFB is removed from the site by helicopter after the installation is completed. (Rick Krishfield)

7. The first IBO deployed this cruise. The ITP (number 42) is on the left, the IMBB is in the center, and the AOFB (with wind generator) is on the right. (Rick Krishfield)

8. Minutes after the previous photo, the weather has turned as the last passengers are removed from the floe. In this picture of the IBO from the air, the IMBB is barely visible down and left of the ITP. (Rick Krishfield)
